Legacy FC 21 takes place July 19 at Arena Theater in Houston. The main card, including Holm vs. Jones, airs on AXS TV.

A pupil of famed trainer Mike Winkeljohn at Jackson-Winkeljohn MMA in Albuquerque, N.M, Holm made her MMA debut in March 2011. The bantamweight fighter defeated Christina Domke via second-round TKO due to leg kicks. Back in February, she made her big-show debut and earned a second-round TKO win over Katie Merrill at Bellator 91.

Holm recently announced her boxing retirement (after earning WBF, IBA Female and WBAN welterweight titles) following a 33-2-3 career record.

Jones, meanwhile, may be best known for her recent fight with Fallon Fox at CFA 11 in May. Prior to the submission loss, Jones won two of three pro bouts following a 6-2 run as an amateur.
